Hackers Leak Data Stolen From UK Electricity Manager Elexon

Hackers Leak Data Stolen From UK Electricity Manager Elexon

The cybercriminals behind the recent attack on Elexon, which manages the electricity market in the UK, have started leaking data allegedly stolen from the company.

Elexon revealed in mid-May that its IT systems were targeted in a cyberattack, but it did not provide any additional details.

It turns out that the company was targeted by a group that launches attacks using a piece of ransomware known as Sodinokibi and REvil, and the hackers have made available some files stolen from Elexon, threat intelligence company Cyble reported on Monday.

Cyble has analysed the leaked files and identified what it has described as “highly sensitive and confidential files and data.” The exposed information includes passport copies, enterprise analysis data, and enterprise renewal application forms.

The REvil ransomware is designed to encrypt files on the compromised system and instruct the victim to pay a ransom to recover them. However, the hackers also steal data from victims to increase their chances of getting paid — victims are told that if they don’t pay up, their files will be made public.

When it disclosed the breach, Elexon said it had been working on restoring impacted IT systems, which suggests that they had no intention of paying the ransom — this is recommended by law enforcement and many cybersecurity professionals.
